Power
Subsystem
This
section
contains
the
removal
and
replacement
procedures
for
the
power
subsystem.
Notes:
1.
All
pluggable
BPA
FRUs
are
replaced
concurrently
with
system
operation
when
the
removal
and
replacement
instructions
are
followed.
Exceptions
to
this
occur
when
multiple
failures
exist
in
the
BPA.
2.
Removal
and
replacement
of
the
entire
BPA
enclosure
(BPE)
is
also
concurrent
with
system
operation,
unless
there
are
multiple
BPE
failures.
Attention:
Be
sure
to
check
for
FRU
redundancy
to
determine
if
the
repair
can
be
performed
concurrently.
If
you
cannot
determine
redundancy,
delay
the
repair
until
the
system
can
be
shut
down.
See
the
for
more
specific
details.
Bulk
Power
Assembly
(BPA)
The
bulk
power
assembly
is
on
the
top
of
the
rack.
This
assembly
provides
power
to
the
whole
system.
There
are
two
sides
to
the
BPA
so
that
power
is
never
completely
removed
from
the
system
unless
the
system
power
is
shut
down,
and
the
power
cables
are
removed
from
the
customer’s
power
source.
Bulk
Power
Regulator
(BPR)
The
BPRs
are
located
in
the
bottom
positions
of
the
bulk
